Last week we brought you news of the “Google Nexus One OLED Display ShootOut” from the guys at DisplayMate, which showed that the display was lacking in features, resolution, and brightness compared to the LCD iPhone 3Gs Screen. Well, the OLED Association has responded saying that while Dr. Soneira found some important issues, his test wasn’t entirely accurate given the technology of OLED.
Dr. Soneira compared images using his own test equipment and concluded that the images on the Nexus I had some serious flaws and showed these images in his report. His diagnosis was that the PenTile OLED subpixel arrangement, the 6-bit color depth, (really 5-6-5) and the high color saturation in the OLEDs were the cause. The Nexus I, however, has a feature that allows the system to use modes of both 5-6-5 bit or 8 bit color depth depending on the image and the designer’s choice. Typically, 8-bits are invoked when the user touches the screen. While Dr. Soneira acknowledges that nonbandwidth-limited content of text, icons and graphics are very crisp, he seems to indicate that the less challenging bandwidth-limited image content is less well rendered. He suggests that the PenTile configuration somehow reduces the resolution and limits the gray scale. This conclusion is just incorrect.
OLED-Display.net has the full response, although it’s a bit difficult to read. I invite Barry Young to send us his rebuttal so that we can post it here as well, hopefully with some better formatting.
